All of the Enhance:DT components share the same noise generation system. This allows any texture to be stirred up
and disturbed. The frequency of the noise can be controlled (Scale) along with the size of the noise
displacement (Magnitude) and the number of noise iterations (Octaves). There is also the ability to
adapt the noise generator with its own magnitude (Noise). Finally, the noise can be modified
over time to create a cyclic noise animation. NOTE To be accurate noise is simply a single slice of a
noise volume. These values can be used repeatedly to generate turbulence. This means that turbulence
is a number of summed noises when the number of "summing's" is usually termed octaves.

The Noise Scale parameter controls the frequency of the turbulence, that is the periodic frequency.
When the scale is at a low value the turbulence will be tight and crinkled and will become increasingly
smoother as the parameter is increased. Unlike the octaves parameter the scale parameter simply changes
the turbulence's fundamental frequency (or overall size).
The figures below show the effect of increasing the Scale value of the diagonal line texture.
As you can see the period of the turbulence increases with the scale value. The allows
larger more sweeping turbulence to be generated. For these samples the octaves parameter
was set to 6, the magnitude parameter was set to 0.2 and the Omega parameter 0.0.

The Noise Magnitude controls the size of the Turbulence that is used to "stir" up the texture.
As the Magnitude value is increased the amount by which the pattern is disturbed is increased.
The figures below show the effect of increasing the magnitude value of the diagonal line texture.
Notice, that the pattern becomes more noisy as the magnitude is increased. For these samples
the octaves parameter was set to 6, the scale parameter was set to 2.0 and the omega parameter 0.0.

NOTE The turbulence function is only called when the Magnitude parameter is a non-zero value.
As the turbulence function takes time to execute the rendering will be slower when it is switched on.

The Noise Octaves parameter controls the number of times noise is summed in order to generate the turbulence.
Turbulence is generated by summing noise with each summed noise being half the magnitude of the previously summed
noise. The number of times the noise is summed is determined by octaves. So, at low values the turbulence will
be smoother and will increase in detail (due to the fact that the summed noise is getting smaller) as the
number of octaves is increased. All this basically means is that the turbulence becomes more "crinkled"
as the number of octaves is increased.
The figures below show the effect of increasing the Octaves value of the diagonal line texture.
Notice, that the pattern becomes more crinkled as the number of octaves is increased. For
these samples the scale parameter was set to 0.5, the magnitude parameter was set to 0.2 and the omega parameter 0.0.

The Noise Omega parameter controls the granularity of the turbulence. The parameter is only used
when it is non-zero. As was detailed in the octaves section the turbulence is generated by summing successive
scales of noise with each scale being half the magnitude of the previous one. The omega parameter actually controls
the scaling of successive noise scales. This effectively means that the turbulence will have a finer grain with
higher values of noise.
The figures below show the effect of increasing the Noise value of the diagonal texture.
Notice, that the pattern becomes finer as the omega parameter is increased. For these
samples the octaves parameter was set to 6, the magnitude parameter was set to 0.7 and the scale parameter 3.0.

The noise or turbulence can be animated on a cyclic basis, This means that after on complete
animation cyclic the texture will return to its ordinal position. One animation cycle is
for Time to go from 0% to 100%. The first thing is to enable the time algorithm for the
noise. This is done by checking the box next to the Noise Time parameter. The time can then
be changed using an envelope to animated over a series of frames. Remember, if the noise
goes from 0% to 100% in a number of frames it can be repeated seamlessly.
The other parameter associated with animated noise is the Velocity. As the name suggests this
controls the speed of the noise over the whole animation cycle. Basically, the higher this
value the more active the noise is.
The figures below show the effect of increasing the Velocity value of the diagonal line texture.
Notice, that the noise goes undulates more quickly as the Velocity is increased. For these
samples the octaves parameter was set to 6, the magnitude parameter was set to 0.2 and the
scale parameter 1.0. For the animation an envelope was created for time that went from 0%
to 100% is a straight line over 8 frames.
